The "moving wall" represents the time period between the last issue
available in JSTOR and the most recently published issue of a journal.
Moving walls are generally represented in years. In rare instances, a
publisher has elected to have a "zero" moving wall, so their current
issues are available in JSTOR shortly after publication.
Note: In calculating the moving wall, the current year is not counted.
For example, if the current year is 2008 and a journal has a 5 year
moving wall, articles from the year 2002 are available.

Terms Related to the Moving Wall

Fixed walls: Journals with no new volumes being added to the archive.

Absorbed: Journals that are combined with another title.

Complete: Journals that are no longer published or that have been
combined with another title.

Abstract

Reconciling tree harvesting with the maintenance of forest bird populations is a major concern of integrated management. Because bird nest predation causes $>$50% of the nest losses in passerines and is known to vary according to habitat characteristics, we explored some aspects of avian nest predation in relation to forestry practices in a boreal coniferous landscape managed primarily for timber production in Quebec. Using artificial tree and ground nests with Common Quail (Coturnix coturnix) and plasticine eggs, we compared the risk of nest predation (1) in experimental riparian forest strips of different widths (20-m, 40-m, and 60-m unthinned strips; $>$300-m control strips; and 20-m thinned strips) and (2) in clearcuts experimentally subjected to different regeneration practices (plantations with chemical and mechanical weeding, and naturally regenerated clearcuts) between 1992 and 1995. The risk of ground nest predation was lower in naturally regenerated clearcuts (5% daily probability of predation) than in control forest strips (27%). We found no evidence that chemical and mechanical weeding affected the risk of nest predation in clearcuts. In forest strips, the predation risk was higher in forest strips 40-60 m wide than in 20-m and control strips. Birds accounted for 13% of predation signs, whereas red squirrels (Tamiasciurus hudsonicus) were the dominant mammalian predators, accounting for 36% of the total predation ($n = 201$ nests preyed upon). In our region, the low predation rates (30% for 24 real nests) and the absence of generalist foragers such as crows, raccoons, and skunks could be attributed to the near absence of human occupation in comparison to forest-dominated landscapes in Europe and northeastern United States.
